- Аннотация: Hydrated fullerene (HyFnC60) is a highly hydrophilic supra-molecular complex consisting of unmodified С60 fullerene molecule enclosed into a hydrated shell. It has been shown in numerous experiments that aqueous solutions of HyFnC60 manifest a wide range of biological activities both in vivo and in vitro even at very low concentrations of HyFnC60. We used a spectrophotometric method and a method of biochemoluminescence to demonstrate that HyFnC60 in concentrations below 10(-9) M down to 10(-23) M stabilizes peroxidase, alkaline phosphatase, and bacterial luciferase against inactivation due to long-term incubation of the enzymes at room temperature and also against heat inactivation. In addition, HyFnC60 was able to "revive" heat inactivated enzymes. These effects cannot be explained by the direct action of the fullerene molecules upon the enzymes. We suggest that the effects of HyFnC60 on the enzymes are related to the ability of hydrated fullerene C60 molecules to organize thick aqueous shells around them. One of the specific properties of water phase in these shells is its ability to optimize redox reactions, which can support enzyme stability against factors deteriorating their structure.
